HZ801 Natural color smooth plate bimetallic composite bearing

The HZ801 Natural Finish Bimetal Composite Bearing is engineered to withstand extreme loads, high temperatures, and demanding operating conditions. Featuring a dual-layer construction—a durable steel backing fused with a high-density copper alloy surface—this bearing offers exceptional load capacity, thermal conductivity, and resistance to wear. Its uncoated "natural finish" design ensures quick break-in periods and stable friction performance, even under continuous heavy stress.

Ideal for applications requiring boundary or mixed lubrication, the HZ801 excels in environments with shock impacts, vibrations, or variable speeds. The copper alloy layer incorporates solid lubricants to provide backup lubrication during startup or intermittent operation, while the steel base enhances structural strength and heat dissipation. Resistant to corrosion, abrasion, and contamination, this bearing is widely used in construction machinery, mining equipment, marine engines, and industrial gear systems. Designed for minimal maintenance and long-term reliability, the HZ801 reduces downtime and extends equipment lifespan. Its compact, lightweight profile allows seamless integration into space-constrained assemblies without sacrificing durability.

Material Features

Steel-backed lead bronze-lined bearing material for lubricated applications, high load capacity and good fatigue properties, have been widely used in automotive, common industrial-like steering gear,power steering, pedal bushes,king-pin bushes,tallgate pivots, mechanical handling, lifting equipment, hydraulic motors, agricultural machines etc.
